is.gd Creator is goodRated 5 out of 5 stars

One click of this toolbar button will generate an is.gd short URL for the current page and copy it to your clipboard. My only complaint is that the toolbar button icon is a distracting bright red color.

Clever add-on! The only annoyance I've found is that when I open twitter pages (which use JS to dynamically load much of the page content) in a background tab, the page doesn't actually start loading until I switch to that tab. Maybe background tabs could postpone their suspension until a couple seconds after losing focus or after first loading?
